We couldn't be happier that Ariana Grande and Jai Brooks are back together and apparently better than ever! Their relationship had a rocky end last year with cheating accusations and arguments on Twitter, but Jai used the social media network for something different this week.

happy birthdays to the most beautiful girl in the world, you are 21!!! you're my world I really love you. here's to so many more memories!!

In honor of Ariana's birthday and this adorable tweet that came with it, we're making Jariana the couple of the week. With both of them going on tour soon, their relationship is going to have to be long-distance.
